So far early benchmarks put the 980 just around (if not better) than the 780 Ti for almost $200 less (980 has a MSRP of $550) and it comes with 4GB VRAM at stock.

I'm seriously considering upgrading for Arkham Knight, Witcher 3, Star Citizen, and Metal Gear Solid V. I want that 1080p/60fps with no dipping. I could even get a second for SLI if I ever want to give 4K gaming a try in a few years.
